sorry to hear about your husband. The first few months of losing someone is usually the hardest especially with sudden loss the shock of it all. Is there a hospice you can call. They have grief groups and such that are extremely helpful plus they will meet with you and talk to you about your loss. Be gentle with yourself. Try to take care of your basic needs such as exercise, eating and grooming. Get a lot of rest. Try to avoid drugs and alcohol if you can. They have a tendency to make things worse. Also a therapist is really helpful at this point. Reach out to supportive people. Give yourself time to heal and feel whatever you need to feel. It will never be the same again. There will probably always be difficult times but it does get better. You get a new normal. Just hang in there. You will make it.
Again so sorry for your loss of your husband. I had four losses this year so I know how hard it is to lose someone.

Post here as often as you need. My prayers are with you.
